Overview
The ACM-31-222M-T is a two-line common mode choke manufactured by Abracon LLC, designed for surface mount applications. It features an impedance of 2.2 kOhms at 100 MHz and supports a maximum rated current of 200 mA. The component has a maximum DC resistance (DCR) of 1.2 Ohms and operates within a temperature range of -40°C to 85°C. Its physical dimensions are 3.00 mm in length, 1.60 mm in width, and a maximum height of 1.8 mm. The device is RoHS3 compliant and utilizes a horizontal four-pad package configuration.
Feature Summary
- Provides common mode noise suppression for signal lines through dual-line filtering capabilities.
- Utilizes a compact surface mount footprint suitable for space-constrained printed circuit board layouts.
- Maintains stable electrical performance across a wide industrial operating temperature range.
Applications
- High-speed data line protection
- Signal integrity enhancement in electronic circuits
- Common mode interference reduction
Procurement Notes
Verify the specific part number ACM-31-222M-T against official Abracon documentation to ensure accuracy. Confirm that the required impedance, current rating, and physical dimensions align with the design specifications. Check for RoHS3 compliance requirements if applicable to the target market. Ensure the selected packaging format meets assembly line needs.
Selection Notes
Select this component when a low-profile, two-line common mode choke is required for high-frequency noise attenuation. The 2.2 kOhm impedance at 100 MHz makes it suitable for suppressing electromagnetic interference on signal traces. Consider the 200 mA current rating to ensure it does not saturate under normal operating conditions. Verify that the 1.2 Ohm DCR is acceptable for the power budget of the application.
Part Context
This component belongs to the ACM-31 series of common mode chokes from Abracon LLC. The series offers various impedance and current ratings within a standardized small outline package. These components are engineered for use in portable electronics and communication devices where space efficiency and effective noise filtering are critical design parameters.
Replacement Considerations
Consult official manufacturer substitution guides for verified equivalents. Cross-referencing requires matching impedance values, current ratings, and physical dimensions to ensure functional compatibility without redesigning the PCB layout.
